Product DescriptionThe WorkSight® PreView® is a solid-state, pulsed radar object detection system designed to alert vehicle operators to the presence of obstacles. The system detects both moving and stationary objects in a pre-defined coverage area and reports the distance of the closest object via visual range indicators and an audible signal to the vehicle operator.

The WorkSight PreView models consist of three major components: an environmentally sealed sensor, an operator display mounted in the cab of the vehicle, and an interconnect cable. The WorkSight PreView system does not require cleaning and is not affected by harsh weather conditions, including temperature extremes, rain, sleet, snow, or fog. The WorkSight PreView Model WS6020 has a twenty foot (six meters) detection range, the WS6015 has a 15 foot detection range (4.5 meters), and the WS6010 has a 10 foot detection range (3 meters).

Sensor / Antenna DescriptionThe antenna assembly transmits and receives low power 5.8GHz radar signals. It then processes the returned signals to determine if an object has reflected any energy back to the sensor and reports this to the operator display. The sensor is designed to process and report detections within ½ of a second allowing the vehicle operator to quickly respond to any object within the detection zone. All connections to a vehicle are accomplished at the sensor. Power is typically obtained from the vehicle reverse lights. The connection to the display unit is through a watertight connector eliminating any potential problems with pin corrosion. Power to the operator display is provided through the sensor interface to the display.

The WorkSight PreView sensor has a continuous Built In Self Test which notifies the operator of sensor failure within a fraction of a second.

Operator Display DescriptionThe operator display provides the vehicle operator with a visual indication of a detected object. The display unit also contains a buzzer* to provide an audible alert that will increase in rate as an object becomes closer, providing the operator with another cue that an object is being detected.

The operator display continuously monitors communication from the WorkSight PreView sensor and in the event of a system failure or malfunction, will notify the operator with a fault indication.

A switch* is provided on the front panel of the display allowing the vehicle operator the ability to adjust the buzzer volume to three different levels or to provide an alarm acknowledge and silence the buzzer.

*OC models do not include the buzzer or switch. Switch functionality is disabledon NVC models.

Item Description

Status LEDIlluminates green continuously after power is applied to the system. The status will change from green to red if a system malfunction occurs.

Range IndicationsIlluminate to give operator a relative distance measurement to the closest detected object. LED’s operate from the left to right, with a closer object resulting in more LED’s illuminated.

Display Buzzer* Sounds audible tones to alert operator of obstacles. The speaker pulse rate will increase as the vehicle gets closer to an object.

Volume Control/Ack Switch*This momentary push button switch allows three different buzzer volume levels to be selected. It can also be configured as an acknowledge switch to silence the buzzer using the Service Tool.

Object Detection CapabilityThe PreView® system is designed to supplement other safety practices and/or devices, and is not to be the sole method of collision avoidance. The machine operator is always the first line of defense when safely operating a vehicle.

The WorkSight PreView system can detect most objects within the detection zone. However, there are some instances where objects can go undetected. Obstacle size, shape, relative location, and composition are all factors determining if, when and where an object is detected. The PreView system operates by transmitting a pulse of very low power electromagnetic energy. Any energy that strikes an object reflects a certain amount of this energy back to the PreView sensor. If the returned energy is of sufficient magnitude, it is used to indicate object presence and determine the object’s distance. While the PreView system can resolve multiple objects, only the object closest to the vehicle is reported to the operator display since it represents the most significant collision threat.

The amount of energy returned is based on a few factors:Size – a larger object usually reflects more energy than a smaller object.Composition – a metal object typically reflects more energy than a non-metallic object. A metallic object at the edge of the maximum detection zone might be detected, whereas a wood object may not.Scattering – a solid object reflects more energy that a non-solid object such as tree branches, gravel, bushes, etc.Shape – complex shapes cause energy to be returned in a very non-uniform way. Very small variations or movement can change detection status.Angle – an object flat side perpendicular to the sensor will reflect more energy than an object at an angle. See below for an example of how angle can affect return energy.

Installation InstructionsBefore you StartPrior to installing the WorkSight PreView Object Detection System take time to familiarize yourself with the installation instructions, theory of operation, and system components. Check the contents of the shipping package and verify the following items are included:

Antenna Sensor (1)Display Unit (1)Interconnect Cable (1)User Manual/Operating Instructions and drill templateSensor Stainless Steel Mounting Hardware1-1/4” x 10-24 Bolts, Hex Locking Nuts, and Washers (4)Display Hardware KitMounting Bracket (1)Mounting Hardware (1)

Sensor / Antenna LocationThe WorkSight PreView sensor mounting location is integral to proper system operation. Ideally the sensor should be mounted on the rear center of the vehicle at roughly 36” (1M) +/- 12” (0.3M) above the ground. The sensor face should be perpendicular to the ground with the “PreView” graphic in normal position. Select a location that will provide some protection from impact and debris while allowing an unobstructed view of the target hazard area.

Important!Before the WorkSight PreView system is permanently installed to the vehicle, verify that the selected sensor mounting location provides a clear detection zone. Temporarily attach the sensor in the proposed mounting location, apply power to the system, and verify that nothing is being detected.

Sensor / Antenna Mounting1. Select the appropriate sensor mounting location.2. The correct mounting configuration is with the sensor’s text in normal reading

position.3. Using the drill template, scribe position marks through the holes. Drill 1/4”

(6mm) holes centered at the marks.4. A 1-1/2” diameter clearance hole is required for the sensor connector and

mating cable connector.5. Secure the sensor to the vehicle with the four supplied 10-24 UNC button

head screws, washers and nuts or equivalent. Apply a maximum torque of 22inch pounds when securing the sensor.

Aux. Output Electrical ConnectionThis sensor provides an auxiliary output that can be used to activate an external backup alarm or other device (white wire). Depending on the system ordered, the cable provided may or may not have provisions to access this output. The aux. output is activated whenever an object is detected. The output is switched from a high impedance state to ground when active and is protected against an over current condition. The maximum operating current is approximately 1 amp, this includes any inrush current. For alarms or other devices that meet the 1 amp maximum current, connect the aux. output wire on the interconnect harness to the ground wire of the alarm or device. For alarms or devices that exceed the 1 amp current limit an intermediary relay must be used.

Display Unit InstallationThe display unit should be mounted where the vehicle operator can easily view it while backing. The ideal location for this is on the dash positioned by either windshield pillar. This will allow the operator view of the display while also looking out one of the side mirrors.

The WorkSight PreView display unit comes equipped with a mounting bracket and hardware. If desired, the display unit can be mounted to the display bracket with the supplied hardware. This bracket can then be mounted in the vehicle cab as desired.

Cable InstallationThe standard interconnect cable between the sensor and display is 30 feet (9.1M) in length. If the distance between the sensor and display is greater than 30 feet, contact Preco for a longer interconnect cable.

Sensor Power ConnectionLocate the vehicle’s reverse light power wire and connect to the red wire on the sensor harness using 18AWG wire minimum. Connect the black wire of the sensor harness to vehicle ground.

Figure 4. Sensor Power Connection

Routing of the cable should start at the sensor. Allow for a small service loop in the cable at the sensor and secure the cable every few feet (~1M) with tie wraps. When ready to enter the cab, drill a 1” (24mm) hole and feed the display connector through. The remaining length of cable is then routed to the display unit and the connectors are latched together. Care should be taken to not route the cable next to heat sources such as the engine and exhausts and areas that may see abrasion or rock damage.

Initial System Power Up and TestOnce the sensor and display are installed, wired, and connected, power should be applied to test correct system operation. When the system is operating correctly in an open field with no obstructions, the status LED indicating green will be the only light illuminated. If any of the detection (yellow) LED’s are lit, check for any vehicle obstruction which may be detected by the sensor. If possible move the sensor so it is not detecting the object(s). If it is not possible to relocate the sensor then consult Preco Customer Service.

If for some reason the system is malfunctioning, one of the yellow LED’s will be illuminated, the status LED will turn from green to red, and the buzzer will make a short stutter sound. Refer to the Error Indications and Troubleshooting sections below to determine the error and solution.

Once the system has been installed, the detection zone should be tested. This test should be performed with two people, one who remains in the cab (the operator), and one who walks through the sensor field at the rear of the vehicle (the assistant). The operator engages the parking brake, depresses the vehicle brake, and places the vehicle in reverse. The assistant then walks through the detection zone while the operator in the vehicle cab notes where the display buzzer activates. By moving about the rear of the vehicle and noting when the display buzzer activates, an accurate detection zone can be mapped.
